We specializes in high-performance tungsten carbide wear-resistant products for demanding industries like mining. Our conveyor belt scrapers are engineered for extreme conditions, where standard steel or polyurethane blades wear out quickly due to highly abrasive materials (e.g., iron ore, coal, granite, sand, or clinker).

Here is a summary of our mining conveyor belt scraper’s key features and specifications:
| Specification | Details | Key Advantage |
|---|---|---|
| Material | Tungsten Carbide + Stainless Steel | Extreme hardness and wear resistance |
| Hardness | Up to 92.5 HRA | Outlasts steel scrapers by over 100x under similar conditions -4 |
| Bonding Method | Vacuum Brazing | Creates a seamless, high-strength bond; 3-5 times longer service life than induction-welded scrapers -2 |
| Operating Temp. | -40°C to 300°C | Suitable for extreme environments (open-pit and underground mines) -2 |
| Scraper Types | P Type, H Type, R Type | Tailored for specific ores (Iron Ore, Coal) and conveyor configurations -2 |
| Application | Secondary Cleaning | Removes residual fine materials after the primary cleaner to reduce carryback -7 |

🔍 Why Tungsten Carbide?
For mining applications involving highly abrasive materials like iron ore, copper, and coal, the choice of material is critical. Compared to standard steel or polyurethane, tungsten carbide offers:
- Superior Wear Resistance: It has a Rockwell hardness of HRA 89-93, far exceeding that of steel (HRA 60-65) -4.
- Longer Lifespan: Tungsten carbide scrapers can last 24-36 months, compared to 6-8 months for steel, significantly reducing maintenance frequency -4.
- Better High-Temperature Stability: It maintains its mechanical properties in extreme heat, where polyurethane may begin to soften -3-4.
🛠️ Which Scraper Shape Do You Need?
ZZ Craftsman offers three standard shapes designed for specific mining conditions -2:
- P Type: Designed for high abrasion environments, such as iron ore processing, where it ensures efficient material removal.
- H Type: Features a reinforced structure to handle high impact applications like coal transportation.
- R Type: Suitable for compact or specialized systems, such as those found in underground mining.
⚙️ Installation and Maintenance
The scraper is designed for integration as a secondary cleaner, typically installed just after the head pulley where the belt leaves the drum -9. It is often used in combination with a primary cleaner to achieve a cleaning efficiency of over 90% -9. The company highlights that our design allows for quick installation to minimize production interruptions, and the durable materials require minimal upkeep -2.
